Some of the false signals can be eliminated by analyzing the stability of the planetary system, conducting photometry analysis on the host star and knowing its rotation period and stellar activity cycle periods.
22.
Even though he did not discover the 11-year sunspot activity cycle, Carrington's observations of sunspot activity after he heard about Heinrich Schwabe's work led to the numbering of the cycles with Carrington's name.
23.
You seem to be asking if a member of another species went to a doctor and complained of symptoms indicating that its sleep / activity cycle was out of synch with its peers.
24.
In addition to the period increase, there is cyclic period change of 0.023 days over 26.7 years, caused by either a third body with a mass of 0.77 solar masses or magnetic activity cycles.
25.
Our biological / perceptual clock, containing a rhythm related to work and time off, is often deregulated during the holidays . Festivities and social activities can cause us to deviate from our normal activity cycle.
26.
TSI varies in phase with the solar magnetic activity cycle with an amplitude of about 0.1 % around an average value of about 1361.5 W / m 2 ( the " solar constant " ).
27.
As a main-sequence star goes through an activity cycle, the outer layers of the star are subject to a magnetic torque changing the distribution of angular momentum, resulting in a change in the star's oblateness.
28.
There are many known modeling paradigms to describe the dynamics of system is represented as an ACD ( activity cycle diagram ) which is a network model of the logical and temporal relationships among the activities.
29.
Measurements of magnetic activity with the 1.5 m telescope at Cerro Tololo Inter-American Observatory show that the star has a 1.6 year magnetic activity cycle which is the shortest cycle measured so far for a solar like star.
30.
These external forces usually contribute to climate change on a time scale, as meteorites strike the earth, on average, every 50 to 100 million years, where as geomagnetic storms occur periodically through the sun s eleven-year activity cycle.
